I've seen a bunch of external drives for Mac. What's the difference of them? Hard Drive is an hard drive, it should work just fine as long as you format it properly, right?
"Mac hard drives" are just HFS+ formatted, while Windows ones are NTFS, and yes, Windows HD works flawlessly if you reformat it. Stores just want extra money with Mac label on it
Of course. I have NTFS partitions in my externals as well so if my iMac fails and I need to access my files in externals, the most important ones are in NTFS partition too.
My 200gig Freeagent for Mac was running out of space(Vista + OS X, ugh) so I ended up buying a 500gig Freeagent. The only difference is the back up software, which doesn't matter after Time Machine.
